The U.S. Special Envoy for Afghanistan Reconciliation Ambassador Zalmay Khalilzad has said that peace deal should guarantee no place for terrorism after a coordinated attack targeted a commemoration ceremony in Kabul on Thursday.

“The ISIS-K attack on civilians gathered to commemorate an Afghan leader demonstrates once again, that a comprehensive #peace agreement must guarantee that terrorism has no place in #Afghanistan’s future,” Ambassador Khalizad said in a Twitter post.

This comes as a group of insurgents targeted a ceremony in Kabul on Thursday which was organized to mark the24th anniversary of the assassination of Abdul Ali Mazari.

The ISIS Khurasan group claimed responsibility for the attack which left at least 11 dead.

However, the Ministry of Interior in a statement said Friday that the Taliban group was involved in the attack.
